Before its relaunch as a gaming website, Friendster was a social networking website that allowed users to connect with their friends. One of the elements of the site were the groups that members could join. This dataset contains the group memberships of all Friendster groups. It is the result of an extensive crawl of Friendster.com at the end of June 2011. It was performed as part of the ArchiveTeam project to archive part of the Friendster data before the service relaunched. The data files list, for each group id, the user ids of the users that were listed on the member list page of that group.
The dataset contains the member lists of 1,449,666 groups. In total, the dataset contains 38,728,037 group memberships from 9,671,720 unique users. In graph terms: the graph contains 11,121,386 nodes and 38,728,037 edges.
